TORPEDO.

Application led July 15, 1921.

To all whom it may concern:

Be it known that I, ALFRED T. VOELKER, a citizen of the United States,residing at Glassboro, in the county of Gloucester and State of NewJersey, have invented certain new and useful Improvements in Torpedoes,of which the following is a specification.

One object of my invention is to make a toy torpedo of a novelconstruction which can be easily and cheaply manufactured and at thesame time can be easily handled and packed without breaking.

Another object is' to. so produce my improved torpedo that while it canbe cheaply and easily manufactured, the parts will hold together untilit is red by throwing the same.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the 'following manner, reference being had tothe accompanying drawings in which- Figure l is a perspective view of atorpedo made in accordance with my invention,

Figure 2 is a perspective view showing a sheet of material, such aspaper, which is rolled and illustrating one step in the formation of oneofthe sections of the shell of my improved torpedo,

Figure 3 is a perspective view showing the rolled sheet yhaving beenpartially folded over one end of the rolled structure and illustratinganother step in the production of my improved tor edo,

Figure 4f shows said section completed,

Figure 5 is a detached perspective view of the sections of the shell 1na position illustrating that one of the sections can be televscopicallyslid in the other section with the closed ends opposed to each other andincluding therebetween a filling of explosive material,

Figures 6 and 7 represent enlarged sectional views of the shell sectionsdetached, and

Figure 8 is a sectional view of the completed torpedo.

Referring to the drawing, my improved torpedo includes a shell 9 made upof two cup-shape sections 10 and 11. These cupshape sections 10 and 11are similarly constructed with the exception that the section 10 is ofslightly smaller external diameter than the -section 11 so that thesections,

which are preferably of cylindrical form,

Serial No. 484,908.

can be slid one into the other by exerting a slight pressure; thefriction between the sections being suflicie-nt to hold them in theirtelescoped position. .as shown in Figure S, and to include therebetweena filling 12 of explosive material. Preferably a coating of adhesivematerial is placed on either or both of the sections so that when theyare forced together they will be secured one to the other. If desiredthe external diameter of the section 10 can be made slightly greaterthan the internal diameter of the section 11 so that it will benecessary during the telescoping m'ovement of the sections to slightlyexpand the diameter of the section 11. This latter also tends tosecurely hold the sections together.

I make the sections 10 and 11 in a novel manner hereinafter describedand since both of the sections are similar with the exception of theirdiameters I will describe the manner of producing one of the sectionsand it will be understood that the other section is similarly) made.

' Referring first to Figure 2, I use a sheet 13 of non-metalliclib-rolls material such as paper; said sheet being made in strip formand this sheet is first rolled as shown at 14. This rolling, if desired,may be done upon a mandrel (not illustrated). I then fold the endportion 15 of the lrolled sheet by first pressing said portion 15 asshown in Figure 3; the initial folding preferably taking place at theportion which includes the outer edge 16 of the sheet. A series of thesefolds are made as shown at 17 in Figure 4 so as to provide a closed end18. The portion of the sheet which is to be folded is preferably coatedwith adhesive material so that when folded the fiaps of the folds willremain in their folded positions. Also by using a thin exible toughpaper the fold when thus made will retain its position; the intersectionof the flaps with the cylindrical surface 19 preferably being made sharpor abrupt. This completes the making of the cup section and bytelescoping two of these sections together with `their closed ends 18opposed to each other, as shown in Figure 8, and having the filling ofexplosive material therebetween, the 'torpedo will be completed. Ipreferably make the sections 10 and 11 of such length that when they areput together the closed end of the section 10 will be ush with the edgeof the open end of the section l1.

It will be noted that by thus making the cup sections that each sectionwill have an integral closed end or in other words an end which isformed of the same material out of which the sides of the section areproduced.

Thile I have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changedWithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, but consider that I am atliberty to make such changes and alterations as fairly come Within thescope of the appended claim.

Having thus described my invention, what naine to this specification inthe presence of two subscribing Witnesses.

ALFRED T. VOELKER.
